It really isn't, and I'm assuming you have never been to Brasil, Bolivia, Peru (Venezuela is out of the question for travelers, but also another example), not to mention Central America and parts of Mexico, I'm sure.
We're talking about inter-generational poverty. People having absolutely no knowledge of what it's like to live a normal life. Poverty that takes you back in time. Some of these places don't have running water or electricity (in fact, no electricity isn't even a big deal in these areas, people are used to it).
Also the dirt roads I mention isn't some rural countryside. I'm talking about poor towns and cities, that have no resources to pave the roads. I still remember TV ads with politicians constantly promising to pave those heavily used roads, but of course it's rampant with corruption.
I think anyone who has not travelled outside of a developed nation, like the US or the UK, probably cannot imagine what people in poor countries consider their every day reality. The contrast is stark, and I'll repeat as many times as necessary, poor people in the US are not really poor. I guess some of them just take their developed nation for granted.
